The Ludlum 4525-Series of Radiation Portal Monitors (RPM) represents state-of-the-art technology for detecting very low levels of radiation in vehicles. The ruggedized detectors offer the greatest detection volume, delivering the best sensitivity at the most affordable price. All detector data are connected to a central computer running Ludlum’s Echo software, which performs all alerting, data logging, and reporting functions. This system can be networked with up to 10 PC stations.

Each gamma detector has been configured to have better resolution than a typical plastic scintillator detector. Additionally, the electronics features low energy and high energy discrimination which allows the system to not alarm on common NORM.
